Key Formulas

• Safety Stock Formula: =NORM.S.INV(95%)*STDEV.P(Demand_Data)*SQRT(Average_Lead_Time_Days) *Adjust confidence level (95%) based on risk tolerance.*
• Reorder Point: =Average_Daily_Demand * Lead_Time_Days + Safety_Stock
• Average Daily Demand (7-day rolling): =AVERAGE(OFFSET([@Date],-6,0,7,1)) — Auto-calculates from historical data
• Inventory Turnover Ratio: =Total_Cost_of_Goods_Sold / AVERAGE(Opening_Inventory_Value, Closing_Inventory_Value)
• Forecasting (Exponential Smoothing): =0.3*Actual_Demand + 0.7*Previous_Forecast — Adjust alpha (0.3) per product volatility

Conditional Formatting Rules

• Stock Levels Below Reorder Point: Red fill with white text for items below threshold.
• Safety Stock Exceeded: Yellow highlight for inventory levels above safety stock (indicating overstock).
• Demand Spike Alert: If daily demand exceeds 2x the 7-day average → green background with bold font.
